CONCRETE CONSTRUCTION.

Specication of Letters ratent.

Patented Oct. 1, 1918.

Application led March 22, 1918. Serial No. 2523,890.

Be it known that I, RALPH A. MnenNi'rY, a citizen of the United States,resldmg at Kansas City, in the county of Jackson andy concreteconstruction.

The object of` my invention is to provide novel, simple, cheap andeiiieient means for securely attaching to concrete walls, veneer facingsand fire proof partitions, and for attaching veneer facings to othercementitions bodies, such as piers, columns, beams, posts, lintels andthe like.

My invention provides further a novel metal stud, which is durable,cheap to manufacture, which may be easily and securely built in a'concrete Wall or the like, and which permits of easy attachment theretoof wall ties at any desired height.

My invention provides still further a novel wall tie, which isparticularly adapted for use in connection with my improved stud, andwhich may be easily and quickly attached thereto.

Other novel features of my invention are hereinafter fully described andclaimed.

In the accompanaying drawing which illustrates the preferred embodimentof my invention,

Figure 1 is a vertical sectional view of a portion of a concrete walland a brick veneer facing attached thereto with my improved studs andWall ties.

Fig. 2 is a perspective view of a portion of an ordinary Woodenvwallform to which are shown temporarily attached two of my improved studs,the upper portions of which nre broken away.

Fig. 3 is a horizontal sectionalview on the line-3 3 of Fig. l.

Fig. 4 is an enlarged perspective view of a portion of one of myimproved studs.

Fig. 5 is a plan view of a rod or wire formed to make a plurality of myimproved wall ties.

Fig. 6 is an enlarged perspective view of one of my improved wall ties.

Similar reference characters designate similar parts 1n the differentvlews.

1f designates a cementitious or concrete body, such as a wall, pier orpost of the ordinary type. 2 designates the brick veneer facingv laid incement or mortar 3 and which is attached to the body 1 by means of myimproved studs and Wall ties.

My improved stud comprises preferably an upright strip of metal 4, suchas rolled sheet steel from opposite longitudinal edges of which are cut,respectively two series of tongues which are bent laterally at rightangles so as to form inwardly extending anchoring arms 5, each of whichis provided at yits inner end `with a projection 6, extending at rightangles thereto.

7 :and 8 designate respectively opposite side boards of an ordinaryWooden wall form, which may be retained in position for receivingy theconcrete in any usual manner. Prior to pouring the concrete into thewooden form, the studs 4 are secured in an upright position to the innersides of the board 7 For temporarily fastening the studs in their properpositlons in the form, each stud may be provided with a plurality ofholes 9, preferably located respectively below the arms 5 in the wideportions of the stud. The holes 9 receive securing devices, such asnails 10, Fig. 2, which are driven into the board 7.

In order that the strain may be equally distributed, the arms 5 of oneseries are,

preferably, disposed in staggered relationship to the arms of the otherseries. By cutting the arms 5 from opposite longitudinal edges of themetal strip, 4, there is no Waste of material. As the arms 5 areintegral parts of the strip, they are rigidlyconnected thereto and will,therefore, be retained in their proper horizontal position, when theconcrete is poured into the mold.

After the concrete has been poured into the form or mold, and has becomesuiiiciently set or hardened, the mold boards Zi and 8 are removed,leaving the upright portions 4 of the studs embedded in the wall flushwith one side surface thereof.

The veneer facing 2 is then laid, and between the desired layers areplaced in the mortar or cement 3 my improved wall ties, each of whichcomprises, preferably, a. piece of rod or wire 11 having its ends bentrespectively into two reversely disposed arcuate hooks 12, which are,preferably, of

like size and which are disposed in the s lme i horizontal plane. Eachhook 12 is prefer ably ,of sufficient diameter to receive the widestportions of the stud 4. The Wall ties may, therefore, be attached at anydesired height to thel stud 4.

When the facing 2 has been laid te a height at which it is desired tobond it to the Wall 1, holes for receiving the hooks 12 are gouged outof the Wall 1 behind the studs 4, and the hooks 12 are thenthreadedthrough the holes which have been gouged in the Wall so a-sf torespectively embrace the different studs, the wall ties being laid`flat- Wise upon the uppermost layer of the facing 2, as shown in-Fgs 1v.and 3.

A layer of morta-r 3 is then placed upon the top layer of'the veneerfacmg so as to cover the Wall ties 11. v

The laying of the veneering 2 is then continued until the veneer facinghas reached a height at Which it is desired to aga-in bond it to theWall 1. At such time, holes are gouged in the wall 1 around the studs 4to receive the Wall ties 11, and the latter are hooked to the studs andlaid in cement or mortar on the top of the' veneer facing in the manneralready described.

By having the hooks .1.2 of arcuate form, a minimum of material need begouged out of the concrete Wall to enable the workman to thread thehooks around the studs.

. By having the wall ties engage the studs intermediate of the anchoringarms 5, and by haring the latter arranged in staggered relationship, thestrain upon the studs is equalized, and a direct pull by thel wall tiesis insured.

By having the hooks 12 revers-ely turned and of like size, the pull uponthe wall tie is direct and equally divided, and either end of the Walltie may be employed to engage a. stud.

The wall ties 11 may be cheaply formed from a single piece of Wire orrod, by forming therein a. series of portions, each having the shape ofthe letter S disposed horizontally, as shown in Fig. 5, each S-shapedportion being cut in two, as indicated by the horizontal dotted lines inFig. A5.

The gage and Width of the metal strip 4. and the thickness of the Wireor rod used to make the Wall ties may be such as shall be required forthe particular purpose in view.

I do not limit my invention to the structure shown and described, asmodifications Within the scope of the appended claim, may be madewithout departing from the spirit of my invention.

That I claim is In a structure of the kind described, a wall, an uprightstud embedded therein at the surface thereof and having anchoring meansembedded in the wall,a veneer facing comprising horizontal layers, and aWall tie secured to the facing between the layers and having a hookpartly encircling and engaging the stud.

In testimony whereof I have signed my name to this specification.

RALPH A. MEGENITY.
